PHP 将 HTML 代码 转换到 UBB 论坛代码

1684网(LieHuo24.Net)教17程 最近给下载栏目增设一键转帖功能,烈火下载栏目是使用DedeCMS构建的,大家都知道dede没有一键转帖功能,于是只好自己写一个,最终实现了。这里记下其中软件简介的HTML转UBB代码。

一键转帖演示:

关于PHP将HTML转UBB代码的问题,笔者在网上找到几个,但都不太好用,于是自己进行了修改和整理,如您有其它需求,可在下面留言。

PHP代码:

Copy to ClipboardLiehuo.Net Codes引用的内容:[www.veryhuo.com]
<?php
$intro = $liehuo-net; // 这里是你获取的变量值。
$intro = str_replace("\n",'',$intro);
$intro = preg_replace("/\<A[^>]+HREF=\"([^\"]+)\"[^>]*\>(.*?)<\/a\>/i","[url=$1]$2[/url]",$intro);
$intro = preg_replace("/\<font(.*?)color=\"#([^ >]+)\"(.*?)\>(.*?)<\/font>/i","<font$1$3>[color=$2]$4[/color]</font>",$intro);
$intro = preg_replace("/\<font(.*?)face=\"([^ >]+)\"(.*?)\>(.*?)<\/font>/i","<font$1$3>[face=$2]$4[/face]</font>",$intro);
$intro = preg_replace("/\<font(.*?)size=\"([^ >]+)\"(.*?)\>(.*?)<\/font>/i","[size=$2]$4[/size]",$intro);
$intro = preg_replace("/\<img[^>]+src=\"([^\"]+)\"[^>]*\>/i","[img]$1[/img]",$intro);
$intro = preg_replace("/\<DIV[^>]+ALIGN=\"([^\"]+)\"[^>]*\>(.*?)<\/DIV\>/i","[align=$1]$2[/align]",$intro);
$intro = preg_replace("/\<P[^>]+ALIGN=\"([^\"]+)\"[^>]*\>(.*?)<\/P\>/i","[align=$1]$2[/align]",$intro);
$intro = preg_replace("/\<([\/]?)u\>/i","[$1u]",$intro);
$intro = preg_replace("/\<([\/]?)em\>/i","[$1I]",$intro);
$intro = preg_replace("/\<([\/]?)strong\>/i","[$1b]",$intro);
$intro = preg_replace("/\<([\/]?)i\>/i","[$1i]",$intro);
echo $intro; // 最后得到UBB代码
?>

现在我们知道了HTML到UBB的转换,那么UBB是否能返回HTML呢?请参照下面的代码,网上收集的。

代码一:

Copy to ClipboardLiehuo.Net Codes引用的内容:[www.veryhuo.com]
<?php
function ubb2html($strCodes) {
$match = array(
"%\[b\](.*?)\[\/b\]%si",
"%\[center\](.*?)\[\/center\]%si",
"%\[url\](.*?)\[\/url\]%si",
"%\[url=(.*?)\](.*?)\[\/url\]%si",
"%\[img\](.*?)\[\/img\]%si",
"%\[fieldset=(.*?)\](.*?)\[\/fieldset\]%si"

);
$replace = array(
"<b>$1</b>",
"<center>$1</center>",
"<a href=\"$1\" target=_blank>$1</a>",
"<a href=\"$1\" target=_blank>$2</a>",
"<a href=\"$1\" target=\"_blank\"><img src=\"$1\" title="veryhuo.com" border=\"0\" onload=\"javascript:if(this.width>550)this.width=500\" title=\"烈火提示:点击查看\"></a>",
"<fieldset><legend>$1</legend><blockquote>$2</blockquote></fieldset>"
);
$strCodes = preg_replace($match, $replace, $strCodes);

return $strCodes ;
}
?>

代码二:
